CARPET-CLEANING MACHINE.

Specification of Letters Patent.

Application filed February 12, 1916. Serial No. 77,842.

To all whom it may concern:

Be it known that I, JULEs DEHON, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Carpet-Cleaning Machine, of which the following is a specification.

My invention consists of a machine adapted to clean and wash carpets, the same embodying a beater, an air-blast, a pipe for applying soapy fluid, brush mechanism, a rinsing-fluid pipe, a device for finally expressing the fluid from the carpet as beaten, washed, b'rushed and rinsed, and drying means, the members employed and the operation thereof being hereinafter set forth.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, as long as they are included in the scope of the claims.

Figure 1 represents a longitudinal vertical section of a carpet cleaning machine embodying my invention. Fig. 2 represents a longitudinal vertical section of a portion of the same. Fig. 3 represents a transverse vertical section of a portion on the line wx Fig. 1. Fig. 4 represents side elevation of a portion thereof. Fig. 5 represents a. longitudinal vertical section of the drying portion of the machine. Fig. 6 represents a partial section, and a partial side elevation of a detached portion of the sprocket chain and the carpet-holding clamp.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates the casing of the machine, the same being supported suitably on the floor 2 of the apartment containing the machine. Above said apartment is the drying chamber 3 in which is mounted a reel on which the cleaned and washed carpet in dry condition will be wound, as will be hereinafter more fully described.

a designates a feed roller whose shaft 5 is mounted on the sides of the casing 1, and has connected with it the sprocket wheels 6 around which pass the endless belts, in the present case of the form of sprocket chains 7, which are guided under the inwardly curved wall 8 of the casing 1, then passed through the openingsin the ceiling of the apartment, and then through the openings 9 in the floor 10 of the drying chamber 3,

and around thesprocket wheels 11. and 12 in said chamber, after which they descend into the apartment below where they are run around the sprocket wheels 13 in said apartment, and finally around the first named. sprocket wheels 6 to which latter power is communicated in any suitable manner, whereby the "sprocket chains 7 are 0perated and receive motion in the direction I means hereinafter described. In the frame of the casing 1, above the feed roller 4 is the hood in which is the beater 16 of suitable construction to which rotation is imparted in any suitable manner, the straps or arms of said heaters being above the piece of carpet, the latter having its face down so that the back thereof will receive the blows of the beater, and so the dust and dirt will be driven through the carpet and drop therefrom into the funneLlike collector 17, at the base 'of which is the exhaust fan or blower 18, the latter having a discharge pipe 19 which may lead into a chimney or stack, or the atmosphere direct as desired.

In order to free the carpet of dust or dirt, I mount above the same, as seen in Fig. 1, a pipe 20 having an outlet upon its under side to direct a blast of air from a suitable source onto the carpet to drive the dust through the latter. from whence it falls into the collector 17. Within the casing 1 is a pipe 21 located below the carpet adjacent the under side of the hood through which soapy or detergent water or fluid may be directed against the carpet so as to saturate the same from below, the droppings from the same being received in the pan 22 supported in the casing below said pipe 21, 23 being an outlet from said pan. 1n the casing above said pan are the brushes 2%, and 26, and between adjacent brushes are the water or fluid conveying pipes 2? and 28 for rinsing purposes, the brushes contacting with the face of the carpet, and the pipes 27 and 28 being adapted to discharge water or iiuid against said faces, said pipes 22? and 28 being connected with a suitable source of water or fluid, and said brushes are rotated by suitable gearing or means on the casing 1, see Fig. 4.

Within the casing 1 back of the carpet is the pressure or squeezing block 29 which is connected withthe heads 30, the latter being slotted and receiving the screws or bolts 31 which admit of the adjustment of said block 29 to impart more or less pressure of said block on the carpet to express from the carpet the fluid or water remaining therein after leaving the brush 26, said fluid dropping into the pan 22.

The clamp 14 which connects the forward end of the carpet with the sprocket chains 7 consists of the cross bars 31 and 32 see Figs. 3 and 6, which are bolted to said sprocket chains and-soearried with the same. The end of the carpet is placed within said bars 31 and 32 andthe wedge 33 driven between said end, and one of said cross bars thus clamping the carpet to said bars.

To assist in guiding the ascent of the carpet I employ the idler'roller 34, which is mounted within the upper part of the casing l rearward of the carpet. It will be seen that the carpet is directed into the hood and advanced, and while advancing it will be beaten, subjected to a blast of air, Washed, brushed, further washed, and brushed, rinsed, and squeezed, after which it is carried upward by the sprocket chains and clamp, over the idler 34 and thence over the roller 15 and into the chamber 3, as seen in 5. A

After the carpet has been subjected to the above-named treatment and the end passed over the roller 15 into the chamber 3, the wedge 33 is withdrawn leaving said end of the carpet free of the clamp and said end is then directed to the reel 35 in said chamber on which it may be wound, said chamber being heated inany suitable manner, if desired, whereby the carpet may be dried.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. In a carpet cleaning machine, a casing, an endless conveyer, means for supporting and operating the same, opposed clamping members carried by said conveyer, and a removable wedge insertible between said members to engage and clamp an end of the carpet and means for directing air and a fluid against opposite sides of the carpet carried by said conveyer.

2. In a carpet cleaning machine, a casing,

an endless conveyer, means thereon for connecting the end of a carpet thereon, means above said conveyer for forcing air through the carpet, means for directing a washing fluid against theopposite side of the carpet and brushes mounted to act against the under side of the carpet.

3. In a carpet cleaning machine, a casing, an endless conveyer, means thereon for connecting the end of a carpet thereon, means above said conveyer for forcing air through the carpet, means for directing a washing fluid against the opposite side of the carpet, brushes mounted to act against the under side of the carpet, and a squeezing device arranged to act against the carpet after it has been acted upon by said brushes.

4. In a carpet cleaning machine, a casing, an endless conveyer, means thereon for connecting the end of a carpet thereon, means above said conveyer for forcing air through 'the carpet, means for directing a washing fluid against the opposite side of the carpet, brushes mounted to act against the under side of the carpet, means for directing a fluid against the carpet between said brushes, and a squeezing dev-ice arranged to act against the carpet after it has been acted upon by said brushes.

5. In a carpet cleaning machine, a casing, an end ess conveyer, means for forcing air through the carpet, impact means arranged adjacent said conveyer to act upon the carpet while it is traveling, a collector beneath said means, means for conducting a fluid against the under side of the carpet, a brush arranged adjacent said conveyer to act upon the carpet, and a receptacle beneath said brush.

6. In a carpet cleaning machine, a casing, an endless conveyer, impact means arranged adjacent said conveyer to act upon the carpet while it is traveling, a collector beneath said means, means for conducting a fluid against the under side of the carpet, a brush arranged adj aeent said conveyer to act upon the carpet, a receptacle beneath said brush, means for forcing the air against one side of the carpet adjacent said impact means, and means for conducting a fluid against the 0p posite side of the carpet between the lastnamedlmeans and said brush.
